' This invention relates to dog racing tracks,

j a'ndhas to doparticularly with improvements? in the construction ofthe same. v The principal object of the invention is to provideanimproved dog racing track .in jwhi'chthe railtrack on which thelure-corn veyer travels is builtfon substantially'the same grade as thecourse, thereby eliminating the time, labor and expense involved'ineither in raising thecourse above the level of the rail track and theground or:lowering the rail track below the level of the course and theground.

, Another important' -object is to provide an improved closure forfoneside of the course" which prevents the/dogs from leaving the course,which providesaprotective mountingfor the electrlclty conductor, andwhich serves as a support for the stationary parts of a 2 olure-hurdling mechanism, all'without obscur- 'ing the vision of thespectators when watching the dogs as they run about the course.

Stillanother object of the invention is to provide an improved lurehurdling mechaclosure for one side of the course.

4 Other objects and advantages of the invention will be apparent tothoseskilled in L the art upon a full understanding of the oon-.

7 dog racingtrack adjacent a hurdle in the course; f

One form of" the invention fispresented herein'for the purpose ofexemplification, but it will of course be understood that the in ventionis susceptible of embodiment in other forms coming equallywithinithescope of the appended claims. V

In the drawing:

Fig. 1 is a transverse section through the 7 v le where it is bothsheltered from the ele- 'ments and guarded from the dogs by an improveddog racing track,taken"at a point Fig. 2 is another section, taken'ontheline 2- 2 of Fig. 1; and

- I Fig. 3 is another section, taken on the line 33 of Fig. 1.

Dog racing tracks of the type l under cons P ticular mechanism 20hereindisclosed-being sideration'ordinarily include a course'lO in the formofan oval pathway abouttwenty feet wide and about a quarter of a milelong, a rail track 11 which extends about the course nism for use inassociation with the improved struction andarrangement ofthe improvedforms a part of the fence l i.

192?. Serial No. 193,104.

along one side of the same, a lure-conveying car '12 mounte'd ontherail-track-and pro pelled by. an electric motor about the same ata highrate of-s'peed, and a suitably supported lure -13c'arried by the car ina position out over the course.

The dog racing track illustrated in the drawing, while of the "typeabove described, differsin several very material repects fromthearrangement ordinarily used. Instead of the course 10 being formedonjthe top of an elevated'embankment, or the rail track ,11 beingpositionedin the bottom of an excavation, either of which constructionsis cusa .tomary in order'to bring the level of the course 10 quite adistance above thelevelof the railtrack11, the course 10 and the rail 1"track 11 are built on substantially the same grade,tthereby eliminatingthe necessity of any filling or'ex'cavating in connection with theconstructionfofthe, dog racing track, which fillingand excavating hasbeen found inthe past to be one ofthe biggest items of cost in'theconstruction of'dog racing tracks.

" T he lure conveyer car 12 preferably travels in the open about theinner side of the course 10; and is separated from thefcourse by a fence14 which is about 3 feet in height. The

fence 14, if positioned about the inner as distinguishable from theouter side of the course, is of open-work construction, being preferablycovered flush on the. side of the same toward: the course with a wire.network 15 of any suitableffabrication. JThe v motor in the conveyer 12receives electric current from a thlld'lall 16 by means of a shoe by aflexible arm 18, and the third rail 16 is positioned close to the baseof the fence 17 which is connected with the conveyer car 7L-shapedhousing 19 which is carried by and If a lure-hurdling mechanismis used, the fence 14 also serves as a support for the sta tionary partsof suchmechanism, the parme. In the form of mechanism shown, the lure 13is carried on the downwardly offset end 21 of an arm 22 which isrotatably mounted in an elevated position upon the superstructure 23 ofthe conveyer car. 12.

When the lure 13 approaches a hurdle 2 1 positioned across the course,the arm 22 is r'o tated a portion of a revolution to swing the lower end21 of the arm into a position wherein the lure 13 will clear the top ofthe hurdle, the turning movement of the arm 22 being effected byengagement of a wheel 25 carried by the upper portion of the arm with anin clined cam 26 carried by the fence in the path ofthe wheel. T hewheel is journaled in the lower end of albracket 27 which is rigidlysecured to the upper portion of the arm 22 on theside of the fence awayfrom the course 10, and, after the wheel has reached the high est point28 on the cam, the arm 22 is caused to swing quickly back againby meansof a spring 29, which spring is secured at one end to the outer end of abracket 30 on the arm,

a and at the other end to a bracket 31 on the those points.

' et 27 being at a sufficient height to clear the high po nt 28 of thehurdles as the car passes The lure-hurdling mechanism above describedmay also be used to remove thelure from the course at the end of a race,it merely being necessary to use a cam on the fence which is high enoughto raise the lure above the level of the top of the fence, and a switchin the rail track whichwill permit the conveyer 12 to be run diagonallyaway from the fenceat the location of such cam, thereby causing the lureto hurdle the fence and disappear from the view of the dogs at theend ofa race.

I claim:

the course at substantially the same level, a fence between the conveyertrack and the course, an electrically operated lure conveyer on the railtrack, a lure arm supported on said conveyer and bentto extend over saidfence to near the racing ground, and a lure carried by the lower end ofsaid arm. said arm a and the support thereof on said conveyer havtweenthe rail track and the course, an elec trically operated lure conveyeron the rail 7 track, and a substantially rigid arm carried by theconveyer above the fence and having a downwardly offset lure-supportingportion above the course.

3. In adog racing track, a course for the dogs, a rail track positionedalongside the course, a fence between the rail track and the course, anelectrically operated lure conveyer on the rail track, means carried bythe conveyer for supporting a lure above the course, an electricalsupply conductor for said conveyer positioned alongside the fence, and aprotective housing for the conductor mounted on the fence.

4.*In a dog racing track, a course for the dogs, a rail track positionedalongside the course, a fence between the rail track and the course, anelectrically operated lure conveyer on the rail track, an arm carried bythe conveyer above the fence and having a -down-,

. fence for coaction with the cam follower.

5. In a dog racing track, a course for the" dogs, a conveyer trackpositioned alongslde the course, a fence for preventing the dogs on thecourse from getting on the conveyer track, an electrically operatedlure-conveyer on the conveyer track. an arm carried by the conveyerabove the fence anda lure carried by the free end of said arm, said armhaving a downward bend on the side extending above said course and beingof sufiicient rigidity and so supported'as to hold said lure free of thecourse.

6; In a dog racing track, a course for the dogs, a conveyer trackpositioned along the course, an electrically operated lure conveyer onsaid conveyer track, a lure arm extending from said conveyer over saidcourse, said arm having a downwardly bent portion extending adjacent thesurface of said course but free therefrom, a lure carried by saiddownward portion of said arm, saidarm having suffia cient rigidity toholdsaid lure free from said 1. In a dog racing track, a course for thedogs,'a conveyer track positioned alongside course, and a mounting forsaid. lure arm on said carriage permitting swinging movement of saidlure arm around an axis substantially transverse to thecourse.

7. 'In a dog racing track, a course for the dogs, a conveyer trackpositioned alongside said course at substantially the same level, a

fence between the conveyer track and the course. an electricallyoperated lure conveyer on said conveyer track, a lure carried by saidconveyer above said course, an electrical supply conductor for saidconveyer positioned adjacent the lower end of saidfence on the sidefacing said conveyer track.

In testimony whereof I have hereunto subscribed my name. i
